For power_supply_get_drvdata() routine to work correctly the driver data
has to be provided when registering power supply, otherwise driver gives up
immediately with these errors:
power_supply main-battery: no battery infos ?!
power_supply main-battery: driver failed to report `status' property: -22

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
